I think he does it if he intends to swap and find the right one (ESP in the case of pt2399 chips and opamps). I know he pushes them hard and have replaced some (and there are a lot of bootleg chips floating around that end up in that part of the world via mailorder).jwar wrote:If it's the chip, I'm socketing that fucker if I have to pull it. LOL. Hopefully it's not one that's hard to come by. I also have some chips and sockets on hand.lordgalvar wrote:If it isn't the switch, it will most likely be that CMOS chip.

..just switches aren't that well made these days).
So if I wanted to try something else, where's a good place to start?
I'd replace the switches first though...most likely that is the problem (I had a bad batch of switches sent to me recently...some poles worked, some didn't).
Kompakt Kassette or memory loss/eccodrone might be good. But with active bass they might not work well (I have to ride the volume on my semi high output guitar for best results and run them first).
I would probably try looking for a DPM?
Ring Mods are kinda like it in some ways, but it is Frequency Modulation. It sounds a lot like the Jen/Grestch Playboy HF Modulator. Holowan makes the thermal wave which is similar to the Hysteresis but has and envelope controlled decay that snaps up like a slow gate. The Hysteresis has two lfos running though which is different. I would kinda look at it as more of a different take on Analog srr and bit crush though...Strange Tales wrote:Got my Hysteresis in yesterday and hot damn. Are all ring mods like this? I might have to get on the ring mod game if so. Pedal is so awesome on everything.
Ring Modulation is the sum and difference frequencies of input and carrier signals that can be used to do a lot of different things (including some overlap with Hysteresis). Ring mod is a specific form of amplititude modulation. FM changes modulates the frequency instead of the amplitude. But the Hysteresis can do amplitude modulation (trem) too. I think what it does is kinda does a fast trem to modulate the signal (ring mod like...playing a trick on the ear but still keeping the pitch related to the original signal and then it modulates that...like a trem made with a pll chip...the holowan does this with envelope and the Hysteresis with lfo)
Basically the carrier wave and Modulator wave to do not change shape based on difference like in ring mod....the frequency of modulation changes at audio speeds.
Ring mod: At least I think.Wikipedia wrote:
It must be the CMOS chip. Fuck me. Oh well. I hope that's what it is at least. It will be relatively easy to take it out, but I'm not looking forward to it. LOL
